Since this topic is quite extensive and needs to be addressed in detail, I thought it prudent to address the kabbalistic views on the twenty-eight "Lunar Mansions," and associated concepts in installments. Readers who are familiar with Hebrew will find a lot of details regarding the "Lunar Mansions," or more accurately "Lunar Times" (
[
Ittot]—"times" ), in the "
Commentary on the Sefer Yetzirah" attributed to the
Raavad. There are facsimiles of both the 1562 and 1806 editions available in electronic format, which you can access directly at:

Further details can also be found in the
Tikunnei Zohar section 69, 101b - 102a.
The twenty-eight "Lunar Mansions" pertain to the twenty-eight days of the lunar month, or more precisely of the "sidereal month." This topic was of particularly importance in Chinese, Japanese and Hindu astrology, and the "Lunar Mansions" featured equally strongly in Islamic Astrology. We should acknowledge the contribution medieval moslem astrologers like Abu'l-Rayhan Muhammad ibn Ahmad Al-Biruni ("
The Book of Instruction in the Elements of the Art of Astrology") made to the study of the twenty-eight "mansions" of the moon, and how greatly "Lunar Astrology" impacted on the Jewish mystics who resided in Moslem lands in the Middle Ages, like for example those who lived in medieval Yemen, where the twenty-eight "mansions" played an important role as "markers" in Yemenite agriculture customs.
Whilst this aspect of Lunar astrology was derived from ancient oriental sources, it was given a unique treatment in Kabbalistic traditions, involving special verses from the Hebrew Bible, the seven "double letters" of the Hebrew alphabet aligned with "seven
Sefirot," "seven seals," as well as the "seven planets" of traditional astrology. These are in turn associated with a set of Divine Names, and finally the entire caboodle was worked into a harmonious whole with the twelve signs of the Zodiac, etc. Most importantly, the Kabbalistic approach to this topic pertains to the
Shechinah, the "Female" aspect of Divinity, or the "Divine Presence" in manifestation, specifically to "Her" being associated with "time." In this regard, the
Zohar (
1:198a) informs us that
(
Et - "time") is "a supernal rung." It continues by asking "And who is this
Et?" to which we are told that it is the letter
(
Heh), and then, by adding the letter
Heh as a suffix to
Et, further elucidates that "it is called
(
Atah)," a term meaning "Now." Daniel Matt explained that the reason for "time" being "a supernal rung" is that the
Shechinah "is known as 'time' since She conducts the world according to a cosmic schedule, enabling phenomenon to unfold in its proper time," and further that "She is also symbolized by the letter
(
Heh), the final letter of the divine name
(
YHVH)." (
Zohar Vol. 3, Pritzker Edition)
Since the
Shechinah is traditionally associated with both "Time" and the "Moon," we can understand why the twenty-eight "Lunar Mansions" are collectively considered to be, as it were, an expression of the "Divine Presence" in manifestation. Furthermore, these twenty-eight Lunar
Ittot (times) are associated with the twenty-eight "qualities of time" listed in
Ecclestiastes 3:1-8 reading:
"To every thing there is a season, and a time to every purpose under the heaven:
A time to be born, and a time to die;
A time to plant, and a time to pluck up that which is planted;
A time to kill, and a time to heal;
A time to break down, and a time to build up;
A time to weep, and a time to laugh;
A time to mourn, and a time to dance;
A time to cast away stones, and a time to gather stones together;
A time to embrace, and a time to refrain from embracing;
A time to seek, and a time to lose;
A time to keep, and a time to cast away;
A time to rend, and a time to sew;
A time to to keep silence, and a time to speak;
A time to love, and a time to hate;
A time for war, and a time for peace."
Note there are fourteen benevolent "times" and fourteen malevolent ones. Kabbalistically speaking these are considered to pertain to the "good" and "bad" time cycles of the twenty-eight "Lunar Mansions," fourteen from the aspect of
Chesed (Mercy or Benevolence) and fourteen from the aspect of
Din or
Pachad (respectively "judgment" and "fear," also
Gevurah). As an aside, it is worth perusing the exposition of
Et Tovah ("good time" also
Et Ratzon ("time of favour") and
Et Ra ("bad" or "evil" time) in "
Gates of Light" (
Sha'arei Orah) by Joseph Gikatilla [see page 103–104 in the Avi Weinstein translation].
Now, the fourteen positive and fourteen negative aspects listed in these verses were arranged in a particular manner in Kabbalah to coincide with the seven "double letters" of the Hebrew alphabet, as well as with the seven attributes or qualities associated with these letters. According to all the manuscripts of the "
Saadia" and "
Long" versions of the
Sefer Yetzirah I have consulted, which is quite different from the much later and currently very popular "
Gra version," the seven "attributes" are associated with the "double letters" in the following manner:
Aryeh Kaplan maintained the order in which Kabbalists associated these attributes with the mentioned twenty-eight "times" in
Ecclesiastes 3, to be "somewhat different than that of the Scripture." ("
Sefer Yetzirah: The Book of Creation in Theory and Practice") He also mentioned that it does not correspond to the order found in the
Sefer Yetzirah. Accordingly the order is said to be:
